<P>PROBLEM TO BE SOLVED: To provide a system and method for providing a material with a uniform micro-structure. <P>SOLUTION: In an embodiment, a shear extrusion system includes an interior mandrel. The interior mandrel includes an expanding shear material section and a contracting shear material section, and the system includes the material. The material is disposed about a portion of the interior mandrel. The system further includes a pressure application device. The pressure application device applies pressure to the material to push and bring the material into contact with the expanding shear material section, and an expanded and sheared material section is obtained. The pressure from the pressure application device is applied to the material to push and bring the expanded and sheared material section into contact with the contracting shear material section, and a contracted and sheared material section is obtained. <P>COPYRIGHT: (C)2013,JPO&INPIT |
